Working Principle of IR Diode SMD

The IR diode SMD operates on the principle of the PN junction. When a forward bias voltage is applied to the diode, electrons from the N-type semiconductor recombine with holes from the P-type semiconductor, releasing energy in the form of infrared light. The intensity of the emitted light depends on the forward current and the material composition of the diode. The IR diode SMD is typically made of materials such as gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit infrared light efficiently. The emitted light has a wavelength range of approximately 700 to 3000 nanometers, making it suitable for various applications.
